Version : 1.2.4
after doing the update (1.1.1 to 1.2.4), all of my NC (nuclear craft) machines don't works with thermals cables ( RF, item.....)

Doesn't seem to be a problem in the latest version (1.2.36)

Well that's odd...could you try breaking the machines and placing them again?

It worked ! Thank you so much

It works but the bug comes back each time the server is restarted
and I need replace machine and cable for it to work again

Could you try using extra utils cables to help narrow down if this is a nuclearcraft problem or a thermal problem?

I just used extrautilities for Item/fluid and draconic crystals for energy and it works

Very strange
